Diagram 5.5 - Circuit Breaker and On/Off Switch
10. If the readings in step 8 are not correct, press the circuit breaker’s reset button and repeat
the measurements in step 8. If the readings are still not correct, replace the circuit breaker
per Procedure 6.6.
11. Test the safety key circuit per Procedure 5.5. If the safety key circuit is functioning correctly,
continue with step 12.
12. Set the on/off switch in the “off” position and remove the AC power from the AC outlet.
Referring to Diagram 5.2, remove the fuse from the lower PCA. With an ohmmeter, measure
across the fuse, it should read approximately, 0.2Ω. If the reading is significantly high,
replace the fuse with an appropriate 3 amp slow blow fuse.
13. The problem has now been narrowed down to either the lower PCA, the data cable between
the lower and upper PCA and the upper PCA.
